Actually, on further reflection, I have nothing useful to add. Only observations. I am probably much younger I am sure than most of you (not my fault, and please don’t hate me for that). At 50 now I was in high school when I did the Epson assembler.
I would probably do best to sit idly by and just enjoy threads like this one. I truly do, too, since I’m interested in computer history (my first machine had 4K, and the assembler was my friend). I am SO impressed with what was done with dozens of K core and early languages. Having written device drivers and the like in assembly, I am impressed with the notion of writing an entire OS .. that’s all. I just had to say something about how impressed I was. Now, I’ll be quiet and enjoy these threads!
